The first VAX Introduced in 1977.
| VAX-11/780 | |
| Codename: | Star |
|---|---|
| Year Introduced: | October 1977 |
| CPU: | KA780 |
| Clock Speed: | 200 ns |
| VUPS: | 1.0 |
This was the first VAX from Digital Equipment Corporation. The VAX was the sucessor to the PDP-11, and in order to make the VAX seem more PDP-11 friendly, they retained the -11 monkier for the first VAX's, hence the 11/780 designation. The 11/780 didn't have normal firmware, instead it loaded it's microcode from floppy.
Emulation
SIMH is the only known emulator for the 11/780. Simh can address up to 128Mb of ram emulating an 11/780. Also the following periphals are emulated:
- CPU VAX-11/780 CPU
- TLB translation buffer
- SBI system bus controller
- MCTL0,MTCL1 memory controllers, MS780C with 4MB memory each, or MS780E with 8MB-64MB each
- UBA DW780 Unibus adapter
- MBA0,MBA1 RH780 Massbus adapters
- TODR time-of-day clock
- TMR interval timer
- TTI,TTO console terminal
- RX console RX01 floppy disk
- DZ DZ11 8-line terminal multiplexer (up to 4)
- CR CR11 card reader
- LPT LP11 line printer
- RP RP04/05/06/07, RM02/03/05/80 Massbus disks, up to eight drives
- HK RK611/RK06(7) cartridge disk controller with eight drives
- RL RL11/RL01(2) cartridge disk controller with four drives
- RQ [[[UDA50]] MSCP controller with four drives
- RQB second UDA50 MSCP controller with four drives
- RQC third UDA50 MSCP controller with four drives
- RQD fourth UDA50 MSCP controller with four drives
- RY RX211 floppy disk controller with two drives
- TS TS11 magnetic tape controller with one drive
- TQ TUK50 TMSCP magnetic tape controller with four drives
- TU TM03 tape formatter with eight TE16/TU45/TU77 drives
- XU DEUNA/DELUA Ethernet controller
- XUB second DEUNA/DELUA Ethernet controller

Operating Systems
The 11/780 was to ship with VMS 1.0.
- VMS 1.0 - ?.0
- 32v
- Ultrix
- BSD (CSRG flavor)
- NetBSD
- OpenBSD
There was also the VAX-11/785, which was an upgraded version.
